Description

Technical Field

[0001] This utility model belongs to the field of wheelchair manufacturing technology, and in particular relates to a rotating base for a wheelchair wheelchair transfer robot. Background Technology

[0002] Wheelchair rims are ring-shaped components installed on wheelchair wheels, similar to bicycle and car rims. They are key components in the wheelchair structure, working in conjunction with the tires to support the weight of the wheelchair and the user, ensuring the wheelchair can move normally.

[0003] Generally, different components of a wheelchair may be manufactured in different workshops or areas. The wheelchair rim may be made in a dedicated production area and then transported to the assembly workshop for assembly using a transfer robot or other tools. During the transfer process, a rotating base for the wheelchair rim transfer robot is designed to provide restraining support for the rim. This base mainly uses a five-pointed star wheel and an arc-shaped bar. Under the action of gears, the arc-shaped bar expands or contracts, which can fix the wheelchair rim on top of the circular tray. This ensures that the wheelchair rim is restrained and supported when placed on top of the transfer robot during the transfer process, reducing the possibility of the wheelchair accidentally falling off during transport. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating base for a wheelchair wheelchair wheelchair transport robot. During the transport process, the wheelchair wheelchair is supported by a binding force when placed on top of the transport robot, thereby reducing the possibility of the wheelchair wheelchair accidentally falling off during transport and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rotating base for a wheelchair wheelchair transfer robot includes a support plate rotatably connected to the top of the transfer robot by bolts. A pentagonal wheel is rotatably connected to the top of the triangular support base. A pentagonal wheel is rotatably connected to the top of the support plate by bolts. A groove is formed at the bottom of the pentagonal wheel. A support rod is slidably connected to the inner cavity of the groove. An arc-shaped strip is welded to the end of the support rod away from the pentagonal wheel. A protruding rod is welded to the bottom of the support rod. A gear is rotatably connected to the bottom of the pentagonal wheel. Five arc-shaped grooves are formed on the surface of the gear. The surface of the protruding rod is slidably connected to the inner cavity of the arc-shaped groove. A small gear is rotatably connected to the bottom of the pentagonal wheel. A support plate is welded to the bottom of the pentagonal wheel. A curved plate is rotatably connected to the bottom of the pentagonal wheel. A spring plate is welded between the support plate and the curved plate.

[0006] Preferably, the surface of the pinion meshes with the gear, and the surface of the bent plate is slidably connected to the surface of the pinion.

[0007] Preferably, a strip is welded to the bottom of the pinion, and a notch is provided on the surface of the support disk.

[0008] Preferably, the notch is located at the bottom of the pinion, and a circular tray is bolted to the top of the pentagonal wheel.

[0009] Preferably, a reinforcing strip is welded to the side of the arc-shaped strip opposite to the pentagonal wheel.

[0010] Preferably, a raised plate is welded to the top of the arc-shaped strip.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model rotates the small gear to drive the gear to rotate, which in turn drives the support rod and the arc strip to slide. At this time, the cooperation of the bent plate and the spring plate fixes the sliding position of the support rod and expands or contracts the constraint range of the arc strip. This achieves the goal of providing a binding support force to the wheel ring when it is placed on top of the transfer robot during the transfer process, so as to reduce the possibility of the wheel ring accidentally falling off when the transfer robot is transporting the wheel ring.

[0013] 2. By setting a notch, this utility model can provide an operating space on the surface of the support plate, making it more convenient for the operator to turn the long strip to drive the small gear.

[0014] 3. By setting the reinforcing strip, this utility model can fix the surface of the arc strip with a constricting force, which can better maintain the original shape of the arc strip, reduce the occurrence of deformation, and protect the surface of the arc strip. Attached Figure Description

[0027] Example 2:

[0028] Figure 1-6This invention illustrates a rotating base for a wheelchair wheelchair transfer robot according to an embodiment of the present invention. It includes: a triangular support base 2 rotatably connected to the top of a transfer robot 1 via bolts; a support plate 3 rotatably connected to the top of the support plate 3 via bolts; a five-pointed star wheel 4 rotatably connected to the top of the five-pointed star wheel 4; a groove 5 formed at the bottom of the five-pointed star wheel 4; a support rod 6 slidably connected to the inner cavity of the groove 5; an arc-shaped strip 7 welded to the end of the support rod 6 away from the five-pointed star wheel 4; a protruding rod 8 welded to the bottom of the support rod 6; a gear 9 rotatably connected to the bottom of the five-pointed star wheel 4; five arc-shaped grooves 10 formed on the surface of the gear 9; and the surface of the protruding rod 8 slidably connected to the inner cavity of the arc-shaped grooves 10. A small gear 11 is rotatably connected to the bottom of the star wheel 4. A support plate 12 is welded to the bottom of the five-pointed star wheel 4. A curved plate 13 is rotatably connected to the bottom of the five-pointed star wheel 4. A spring plate 14 is welded between the support plate 12 and the curved plate 13. A circular tray 17 is fixedly connected to the top of the five-pointed star wheel 4 by bolts.

[0029] Working principle: When using this utility model, the user rotates the long strip 15 to drive the small gear 11 to rotate. Under the action of meshing, the small gear 11 drives the gear 9 to rotate. Then, under the action of the arc groove 10, it pushes the protruding rod 8 to drive the support rod 6 to slide in the inner cavity of the slide groove 5. At this time, the cooperation of the bent plate 13 and the spring plate 14 can prevent the small gear 11 from reversing during rotation, thereby limiting and fixing the sliding position of the support rod 6, and expanding or contracting the constraint range of the arc strip 7. In order to provide a binding support force for the wheel ring when it is placed on top of the transfer robot 1 during the transfer process, the transfer robot 1 reduces the possibility of the wheel ring accidentally falling off during the transport of the wheel ring.

[0030] In summary: This wheelchair wheelchair wheelchair transfer robot uses a rotating base. By turning the pinion 11, the gear 9 rotates, which in turn causes the support rod 6 and the arc-shaped strip 7 to slide. At this time, the cooperation of the curved plate 13 and the spring plate 14 fixes the sliding position of the support rod 6 and expands or contracts the constraint range of the arc-shaped strip 7. This achieves the goal of providing a restraining support force to the wheelchair wheelchair when it is placed on top of the transfer robot 1 during the transfer process, thereby reducing the possibility of the wheelchair wheelchair accidentally falling off during transport.
